A spherometer has 250 equal divisions marked along the periphery of its disc, and one full rotation of the disadvances by 0.0625 cm on the main scale. What is the least count of the spherometer ?

Text Solution

Verified by Experts

The correct Answer is:
`2.5 xx 10^(-4)` cm

L.C. = `(0.0625)/(250)` cm = `2.5 xx 10^(-4)` cm
